Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of communication system and device.
Background technology
Development along with modern communication technology, access network must satisfy the access requirement of miscellaneous service network and user to the popularity of business demand, multifarious requirement, and development in future is the incorporate FSAN network of network access layer broadband and narrow band access.In order to guarantee that there is abundant interface type in system, satisfy requirements of different users, what existing systems generally designed is Full Featured backboard, integrated all buses on backboard, the access of compatible various interface plug-in card.
As shown in Figure 1, have only a backboard in the present access device usually, for satisfying the needs of different interface type, the integrated data/address bus of nearly all type, control bus and power bus on the backboard, cost is very high, and subsequent expansion is also bad.For example, for broadband access equipment, because towards the application that broadband xDSL inserts, GPON inserts and narrow band service inserts, need to provide time division multiplexing tdm bus, gigabit Ethernet GE bus and 10GE bus or 4GE bus or the like on the backboard simultaneously, for considering constantly to promote follow-up access capability, may also need to reserve various expansion bus simultaneously.
This design can't be distinguished configuration at the application of different business demand, and printing board PCB is bigger, and the PCB number of plies is many, and various connector is also more complete, and the increase that inevitably brings cost has greatly reduced the competitiveness of system.Simultaneously, bussing technique development now is swift and violent, and the update cycle is also very fast, the easy smooth upgrade of system and the characteristic of easily expanding are also extremely important, when how to accomplish easily expansion, not bringing rolling up of cost, is the problem that must need consider when design.And existing backboard integrated in advance all buses, cause follow-up when having new bussing technique to occur, can not be by simple method upgrade-system, and need redesign backboard and total interface plate.And the bus that system reserves is because also there is very big risk in technological uncertainty.In case business demand changes, when needing redesign, need to develop again Full Featured backboard again, the development﹠ testing cycle is very long.
Summary of the invention
The object of the present invention is to provide a kind of communication system and device with modularization backboard.
Technical scheme of the present invention: a kind of network equipment, comprise backboard and business board, business board links to each other with backboard by bus, it is characterized in that: described backboard further comprises basic backboard and sub-backboard, wherein basic backboard is in order to provide basic system bus, sub-backboard is in order to provide the system bus of expansion, and sub-backboard links by expansion interface and basic backboard.
Beneficial effect of the present invention: the present invention separates the basic function of backboard with expanded function, carry out modularized design, can be according to the business demand of different user, different back board systems is formed in collocation flexibly, make cost control accomplish optimum, for most basic application, can effectively reduce system cost.And extensibility is good, can release corresponding sub-backboard fast according to up-to-date bussing technique, in conjunction with basic backboard, makes up new system platform, satisfies the business demand of bringing in constant renewal in.In addition, ripe basic backboard can be easy to directly be used by other system, has greatly shortened system development cycle.

Embodiment
As shown in Figure 2, communication system of the present invention comprises core network device and access network device, and access network device is in order to be linked into user terminal on the core network device.Backboard and business board are installed in the access network device, and business board links to each other with backboard by bus.
As shown in Figure 3, the core bus cutting of the network equipment of the present invention is a plurality of parts, forms basic backboard 1 and some sub-backboards, as sub-backboard 2, sub-backboard 3 etc., sub-backboard 2,3 links by expansion interface and basic backboard 1, and connecting mode is that cable or flexible board connect.
The main integrated data/address bus of arrowband special use of sub-backboard 2 is as time division multiplexing tdm bus and arrowband power bus.Basic backboard 1 and sub-backboard 2 collocation can be used for the application of the system that wide and narrow strip supports simultaneously.As both supporting basic ADSL/VDSL broadband services, the service accessibility of arrowband is provided simultaneously, comprise traditional business such as traditional voice telephone service POTS, E1/T1, Inverse Multiplexing over ATM IMA.
The main integrated high speed growth data bus of sub-backboard 3, as 10 gigabit Media Independent Interface XGMII (10Gigabit Media Independent Interface), 10 gigabit attachment unit interface XAUI (10Gigabit Attachment Unit Interface) bus etc., satisfy the application of high speed bandwidth business demand, as point-tor point P 2 P (point-to-point), passive optical network PON, VDSL2 etc.
Certainly, be the demand of meeting demands of multiple service access, can realize that sub-backboard can be according to the characteristic of follow-up business by the mode of the sub-backboard of flexible expansion, divisions such as bandwidth requirement, being not limited to is two sub-backboards above-mentioned, can also be to reserve wireless access etc.
The present invention separates the basic function of backboard with expanded function, carry out modularized design, can be according to the business demand of different user, different back board systems is formed in collocation flexibly, make cost control accomplish optimum,, can effectively reduce system cost for most basic application.And, good according to the extensibility of backboard of the present invention, can release corresponding sub-backboard fast according to up-to-date bussing technique, in conjunction with basic backboard, make up new system platform, satisfy the business demand of bringing in constant renewal in.In addition, ripe basic backboard can be easy to directly be used by other system, has greatly shortened system development cycle.
More than be explanation, in concrete implementation process, can carry out suitable improvement, to adapt to the concrete needs of concrete condition method of the present invention to the specific embodiment of the invention.Therefore be appreciated that according to the specific embodiment of the present invention just to play an exemplary role, not in order to restriction protection scope of the present invention.
